Photorespiration, C4 Pathway and CAM metabolism pathway – Photosynthesis in plants (Part V)

By | September 23, 2021

Evolution (cumulative changes in a population or species through time), is crucial for survival and flourishing of all species or populations. According to endosymbiosis theory, all the eukaryotic life which we see today had evolved from the Archaea bacteria. Evolution has also played an important part in process of photosynthesis- from bacteria to plants. Photosynthesis… Read More »
